{"id":"GHSA-xvx8-77m6-gwg6","summary":"OpenClaw: Sandbox `writeFile` commit could race outside the validated path","details":"## Summary\nIn affected versions of `openclaw`, the sandbox fs-bridge `writeFile` commit step used an unanchored container path during the final move into place. An attacker racing parent-path changes inside the sandbox could redirect the committed file outside the validated sandbox path.\n\n## Impact\nThis is a sandbox boundary bypass. In-sandbox code could win a time-of-check-time-of-use race and cause host-approved `writeFile` operations to land outside the validated writable path within the container mount namespace.\n\n## Affected Packages and Versions\n- Package: `openclaw` (npm)\n- Affected versions: `\u003c 2026.3.11`\n- Fixed in: `2026.3.11`\n\n## Technical Details\nThe hardening work for anchored remove, rename, and mkdir operations did not fully cover the `writeFile` commit path. The final `mv` still used the raw target path, leaving a race window between safety revalidation and the in-container commit step.\n\n## Fix\nOpenClaw now anchors the `writeFile` commit path to the canonical parent directory before the final move. The fix shipped in `openclaw@2026.3.11`.\n\n## Workarounds\nUpgrade to `2026.3.11` or later.","aliases":["CVE-2026-32977"],"modified":"2026-04-06T23:06:26.145186Z","published":"2026-03-13T15:47:15Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-03-13T15:47:15Z","nvd_published_at":null,"cwe_ids":["CWE-367"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-xvx8-77m6-gwg6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32977"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.3.11"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-sandbox-boundary-bypass-via-unanchored-writefile-commit-path"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.3.11"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-xvx8-77m6-gwg6/GHSA-xvx8-77m6-gwg6.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:H"}]}
